To allwhom it may concern: i v

Be it known that LDnvru H. IRLAND, of New"Yorlr city, in the State, of'New York, have invented certain new and useful Improvements in Portable Domestic Gas Apparatus; anddc hereby declare that the following is :a full, clear, arid exact description thereof, reference beinghpd to the accompanying drawings and to the lettcrsi'of reference marked thereon, making a part Ofltll'iS speciiication. v

The nature of my invention 7 consists in the construction. and arrangement of a portable domestic coal-gas gii'iierator and steam-heater combined, as hereinafter more fully set forth.

In order to enable others skilled in the art to which my inyontion appertains to make and nseti' esame', l will nowpro'ceed to do scribe its constructiouand operation,.referring to the annexed drawings, in Which Figure 1 iso perpcctire View of the entire machine. Fig. 2 is a crosssection of the furnace; Fig. 3, a vertical section of the gasholiler; Fig/ha section oithc condenser; Fig. 5, a section of the purifier; Fig. 6, a section of vthe hydraulic main and scrubber; and Fig. 7, a detailed view of the retort' l A represents the shell of thefurnace, pro vidod on top with ahorizontal steam-boiler, B, which is connected near each end with a system of horizontal and vertical' pipes, C 0, arranged along the sides on the inside of the or constituting part of the boiler, the socalledboilcr B on top forming also the steam-dome, from an outlet, a, on the top of which steam may be conducted through suitable pipes to radiators of any ordinary construction for heating the building by steam.

0n each side of the furnace is a lining, D, of tiling, extending from the bottom upward for a suitable distance; and between this tilelining and the pipesU, on each'si'de, is a sliding sheet-metal damper, D. The lining l) and damper l) are both provided with a number oi perforations, a, corresponding with each other. The dampers I) may be moved for ward and backward by means of suitable handles at t'ucffron t oi the furnace, so as to entirely uncover the perforations in the tiling, or partially or entirely close the same, and thereby regulatethe heat to the boiler.

In summer time, or at any time when no steam is to be used, the tile-lining isito extend all the way up to the top.

In the top of the furnace is a retort, E, of ordinary construction, provided at its frontend with-a lid, G, having the usual flange b fitting within the end of the retort. 'lo seal the retort I use apacking, d, of isingla'ss cut out to fit around the flange b, as shown. This isinglass packing takes the place of the common iutin g, and is far superior thereto, as itis al-- ways in place and can be used over and over again, saving both time and labor.

From the sides of the retort project twohook-shaped arms f f, in which is. placed a shaft, h, provided with an eccentric, e, which by turning the shaft 7 is brought against the lid (1: to press the same into its place on the end of the retort and hold it there. i

From the retort E the gas passes through a pipe, E, into the hydraulic main G which also forms a scrubber. Through the top bf.

the combined scrubber and hydraulic main G passes a pipe, G, which is closed at itslower end and perforated,its'entire length within the main, as shown. To this pipe is secured a series of horizontal perforated diaphragrns, G fitting within "the-main G.

- 'lhe gas-pipe E enters the main below the bottom diaphragm; and the top oi-the pipe G is by a pipe, a, connected with the'steamboiler orv dome B, so that steam will be conducted into said pipe G? from the boiler, and escape through the perforations in the pipe in to the main and scrubber. The steam thus admitted under low pressure permeates and acts upon the ascending gas to take out the ammonia. fThis process of scrubbing by means oi steam under low pressure is thorough and efficient, and all the condensation settles down to the bottom of the main G, from whence it is taken off automatically by a si-' w phon, H, and conducted to the fire-box of the furnace and consumed.

It will thus be seen that there is no necessity oi cleaning out the scrubber. Iii-cleans itself by the tar being drawn oif automatically from the bottom oi the hydraulic main to the furnace, Where it is consumed.

From the top of the combined hydraulic maiuand scrubber the scrubbed gas passes to the condenser, consisting of abox, I, divided by partitions, and provided with upright pipes 1 connected at the top in pairs by elbowpipes 1 v This construction of the condenser is sub stantially the same as heretofore sometimes used; but I provide the elbow at the top of each pipe, through which the gas passes up; \i'a'rd, with an interior packing, i, or" sponge or similar absorbent material, which retards the flow oi the gas, so that the condensation will be the more thorough. This sponge-packing also absorbs the moisture contained in the gas, which moisturethen settles down in the bottom of the condenser, and is carried oh by a From the condenser the gas passes to the purifier J, which has a water-sealed cap, J as bark, shell-lime, and copperas thoroughly mixed together. By repeated and long-continued experiments I have found that this mixture takes the sulphur fully out of the gas more thoroughly than is done by the purifying materials or mixtures heretofore generally employed, and this mixture need not be renewed near as often as those now used.

If a poor quality of coal is used to make the gas, the chamber J is provided at the top with a pan-shaped perforated diaphragm, K, which penis to be tilled withwooi for the gas to pass through, whereby the gas is enriched and its illuminating power greatly increased.

From the purifier the gas passes, as de. scribed, to thegas-holder B, which moves up and down in the usual manner in oI'water-seel, R. The inner shell or eylinderot' this waterseal is closed at the top, and within the same is laid a coil of pipe, R close against the inside thereof, and extending the en tire distance from top to bottom of the. water-seal. This coil is to be connected with the steam-boiler, so that steam can be passed through it in the winter time to prevent the water in the seal from freezing. This is applicable to both portable and stationary gas-works.

I am aware that steam has been used for this purpose before; but in such cases it has only been applied at the top of the water-seal when the same is built in the ground. By

my invention of applying the steam through a coil from top to bottom of the water-seal the entire height of the seal is acted upon by the steam, and thus the construction of sta tionary gas-works may beimade less expensive and costly. I

Having thus fully described my invention, what I claim as new, and desire to secure by Letters Patent, is-- 1. In a furnace forportable domestic gas apparatus, the combination, with the boilertubes 0, of the perforated tile-lining D and the sliding peribrated dampers D, for the purposes herein set forth. a

2. In a gas-retort, a packing or seal, d, of

isinglass interposed between the lid and the end of the retort, as set forth.

3. In a portable domestic gas apparatus, the hydraulic main and scrubber (3, having the pigi'orated steam-pipe G and the series of per rated diaphragms G substantially as and for the purposes herein set forth.

6L In a portable domestic gas-machine, the r gas-condenser composed of the partitioned box Lnpright pipes P, and elbow-connections 1 the packing hot sponge or similar absorbent material, placed in the elbows, substantially as and for the purposes herein set forth.

In testimony that I claim the foregoing 1 have hereunto set my hand this 2d day of May,1877. I
